Nesting in the Cloud

Nesting of hypervisors, known as a nested virtualization, makes it possible to set up a complete virtualization scenario with a data center, storage, and high-availability functions on a laptop. In this article, we show you how, with Linux iSCSI and free VMware trial versions.

Some modern laptops include hardware that only a few years ago would have been found on a major server: 64-bit CPU, dual or quad-core, 8GB of RAM, and a 500GB hard disk. Devices like this can handle simple desktop or office applications without breaking a sweat; only special applications, such as software development with a J2EE application server and an IDE or HD video editing, really stress the 8GB of RAM.
